# VK MCP Server

Model Context Protocol (MCP) server for [VKontakte](https://vk.com) (VK) — the largest social network in Russia and CIS countries.

This server allows AI assistants (Claude, Cursor, Windsurf, VS Code, etc.) to interact with VK through a standardized MCP interface.

## Features

- **180+ VK API tools auto-generated from the official schema** (full set available with `VK_MCP_MODE=all`; safe defaults expose a smaller subset) — users, wall, groups, friends, photos, videos, messages, market, stats, stories, polls, and more
- **Auto-generated from VK API schema** — always up-to-date with the official API
- **Read/Write/Money mode filtering** — restrict AI to read-only, allow non-financial writes, or enable financially sensitive methods
- **Section filtering** — include or exclude specific API sections (e.g., disable `ads`, `secure`)
- **`.env` support** — load token from environment file for local development
- **VK upload API helpers** — exposes upload-server and save methods for media workflows
- **ESM-based** — modern Node.js module system
- **Multiple transports** — stdio (for Claude Desktop / Cursor), Streamable HTTP and SSE (for remote MCP clients like Grok)

## Prerequisites

- Node.js ≥ 18
- VK Access Token with required permissions

## Installation

### Option 1: Run with npx (no install)

```bash
npx full-vk-mcp
```

### Option 2: Install globally

```bash
npm install -g full-vk-mcp
full-vk-mcp
```

### Option 3: Clone from GitHub

```bash
git clone https://github.com/ssm82/full-vk-mcp.git
cd full-vk-mcp
npm install
node src/index.js
```

The VK API schema is downloaded **automatically** on the first run. No manual steps needed.

## Configuration

### 1. VK Access Token

Create a `.env` file in the project root:

```bash
VK_ACCESS_TOKEN=your_vk_token_here
```

Or get a token from:
- [vkhost.github.io](https://vkhost.github.io/) — quick token generator
- [VK Dev](https://dev.vk.com/) — official developer portal

**Required permissions depend on your use case:**
- `wall` — posting and reading wall
- `photos` — uploading photos
- `groups` — community management
- `friends`, `messages`, `market`, `stats` — as needed

> **Security:** Never commit your token to git. The `.env` file is already in `.gitignore`.

### 2. Choose a Profile (Recommended)

Instead of manually configuring sections and methods, use a built-in profile via `VK_MCP_PROFILE`:

```bash
VK_MCP_PROFILE=minimal npx full-vk-mcp
```

| Profile | Mode | Description | Warning |
|---------|------|-------------|---------|
| `minimal` | read | Essential read methods | Safe |
| `social` | read | Users, friends + extras | Safe |
| `content_read` | read | ~25 content viewing methods | Safe |
| `content_publish` | all | ~20 content creation methods | Can publish |
| `community_manager` | all | Wall, board, groups management | Can modify communities |
| `messenger` | all | Messages + user info | Requires `messages` scope |
| `analytics` | read | Stats, wall, groups insights | Safe |
| `money` | money | All financially sensitive methods allowed by money-mode filtering | **Financially sensitive** |
| `ads` | money | Ads API + helper methods | **Can spend money** |
| `market` | money | VK Market + upload helpers | Can modify shop |
| `commerce` | money | Market, orders, store, gifts, donut | Financially sensitive |
| `search` | read | ~10 search methods | Safe |
| `full_read` | read | All read methods except ads/secure | Safe |
| `full` | all | **All VK API methods** | **Development only** |

Profiles can be extended with environment variables:

```bash
VK_MCP_PROFILE=social VK_MCP_INCLUDE_SECTIONS=wall npx full-vk-mcp
```

> **Env extends profile:** list variables (sections, methods, excludes) are merged with the profile; scalar `mode` is overridden by env.

### 3. MCP Client Setup

#### VS Code (with Copilot / Claude / etc.)

Create `.vscode/mcp.json`:

```json
{
  "servers": {
    "vk": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "full-vk-mcp"],
      "env": {
        "VK_ACCESS_TOKEN": "${input:vk-token}",
        "VK_MCP_PROFILE": "minimal"
      }
    }
  },
  "inputs": [
    {
      "type": "promptString",
      "id": "vk-token",
      "description": "VK Access Token",
      "password": true
    }
  ]
}
```

For local development from a cloned repository, use:

```json
{
  "command": "node",
  "args": ["/absolute/path/to/full-vk-mcp/src/index.js"]
}
```

#### Cursor

Create `.cursor/mcp.json`:

```json
{
  "mcpServers": {
    "vk": {
      "command": "npx",
      "args": ["-y", "full-vk-mcp"],
      "env": {
        "VK_ACCESS_TOKEN": "your_token",
        "VK_MCP_PROFILE": "social"
      }
    }
  }
}
```

#### Claude Desktop

Edit `claude_desktop_config.json`:

- **macOS:** `~/Library/Application Support/Claude/claude_desktop_config.json`
- **Windows:** `%APPDATA%/Claude/claude_desktop_config.json`
- **Linux:** `~/.config/Claude/claude_desktop_config.json`

```json
{
  "mcpServers": {
    "vk": {
      "command": "npx",
      "args": ["-y", "full-vk-mcp"],
      "env": {
        "VK_ACCESS_TOKEN": "your_token",
        "VK_MCP_PROFILE": "minimal"
      }
    }
  }
}
```

For local development from a cloned repository, use:

```json
{
  "command": "node",
  "args": ["/absolute/path/to/full-vk-mcp/src/index.js"]
}
```

#### Windsurf / Other MCP Clients

Use the stdio transport and provide `VK_ACCESS_TOKEN` via environment variables.

### 4. Transport Mode

By default, the server uses **stdio** transport for local MCP clients. To enable remote connections, switch to HTTP:

| `VK_MCP_TRANSPORT` | Use case |
|--------------------|----------|
| `stdio` (default)  | Claude Desktop, Cursor, VS Code, Windsurf |
| `http`             | Grok, ChatGPT, remote MCP clients |
| `sse`              | Same as `http` (both endpoints enabled) |

```bash
# HTTP mode for remote clients
VK_ACCESS_TOKEN=your_token VK_MCP_TRANSPORT=http npx full-vk-mcp
```

## Environment Variables

| Variable | Default | Description |
|----------|---------|-------------|
| `VK_ACCESS_TOKEN` | *(required)* | Your VK API access token |
| `VK_MCP_PROFILE` | — | Built-in profile name (`minimal`, `social`, `full`, etc.) |
| `VK_MCP_MODE` | `read` | `read` — read-only, `write` — non-financial writes, `money` — financially sensitive, `all` — everything |
| `VK_MCP_INCLUDE_SECTIONS` | — | Comma-separated whitelist of API sections. Without a profile, safe subset (`users`, `groups`, `wall`, `friends`, `photos`) is used |
| `VK_MCP_EXCLUDE_SECTIONS` | `ads,secure,market,orders,store,gifts,donut,votes` *(without profile / without explicit includes)* | Comma-separated blacklist of API sections. Skipped when `VK_MCP_INCLUDE_SECTIONS` or `VK_MCP_INCLUDE_METHODS` is set |
| `VK_MCP_INCLUDE_METHODS` | — | Comma-separated whitelist of methods (e.g., `users.get,wall.get`) |
| `VK_MCP_EXCLUDE_METHODS` | — | Comma-separated blacklist of methods |
| `VK_MCP_MAX_TOOLS` | — | Limit the number of exposed tools |
| `VK_MCP_TRANSPORT` | `stdio` | Transport type: `stdio`, `http`, or `sse` |
| `VK_MCP_PORT` | `3000` | HTTP port (falls back to `$PORT` for PaaS like Render) |
| `VK_MCP_HOST` | `127.0.0.1` | Bind address. Use `0.0.0.0` for public hosts |
| `VK_MCP_AUTH_TOKEN` | — | Bearer token for HTTP transport auth (required when binding to non-loopback) |

### Mode Filtering

The server automatically classifies each VK API method into risk levels:

| Mode | Description | Sections |
|------|-------------|----------|
| `read` | Read-only methods | Safe subset: `users`, `groups`, `wall`, `friends`, `photos` |
| `write` | Read + non-financial writes | Can modify your account (post, edit, delete, send, etc.) |
| `money` | Financially sensitive only | `ads`, `market`, `orders`, `store`, `gifts`, `donut`, `votes`, selected `secure.*` |
| `all` | Everything | Read + write + money — no restrictions |

- **Read** methods — `get*`, `search*`, `is*`, `are*`, `check*`, `resolve*`, `find*`, `count*`, `lookup*`, `list*`
- **Write** methods — everything else (post, edit, delete, send, etc.)
- **Money** methods — any method in financial sections or explicitly tagged (`secure.getAppBalance`, etc.)

Use `VK_MCP_MODE=read` to prevent the AI from making any changes to your VK account.
Use `VK_MCP_MODE=money` when you need ads, market, or payment-related tools.

## Running Locally

With npm/npx:

```bash
VK_ACCESS_TOKEN=your_token npx full-vk-mcp
```

With a cloned repository:

```bash
# With .env file (recommended for development)
node src/index.js

# Or inline
VK_ACCESS_TOKEN=your_token node src/index.js

# Use a profile
VK_ACCESS_TOKEN=your_token VK_MCP_PROFILE=minimal node src/index.js

# Read-only mode
VK_ACCESS_TOKEN=your_token VK_MCP_MODE=read node src/index.js

# Include only specific sections
VK_ACCESS_TOKEN=your_token VK_MCP_INCLUDE_SECTIONS=users,wall node src/index.js
```

### HTTP Mode

```bash
# Start HTTP server (localhost only, no auth)
VK_ACCESS_TOKEN=your_token VK_MCP_TRANSPORT=http npx full-vk-mcp

# With custom port
VK_MCP_TRANSPORT=http VK_MCP_PORT=8080 npx full-vk-mcp

# Public deploy (auth required)
VK_MCP_TRANSPORT=http VK_MCP_HOST=0.0.0.0 VK_MCP_AUTH_TOKEN=your_secret npx full-vk-mcp
```

### Test HTTP endpoint

```bash
# Health check
curl http://127.0.0.1:3000/health
```

For full MCP protocol testing, use the MCP Inspector:

```bash
npx @modelcontextprotocol/inspector
```

Then select:

```text
Transport: Streamable HTTP
URL: http://127.0.0.1:3000/mcp
```

Streamable HTTP is session-based. A raw `tools/list` request must be sent only after an `initialize` request and with the returned `Mcp-Session-Id` header.

In the Inspector UI select **Streamable HTTP** and enter `http://127.0.0.1:3000/mcp`.

Arguments: { "count": 5 }
```

### Search for users

```
Tool: vk_users_search
Arguments: { "q": "Ivan Ivanov", "count": 10 }
```

}
```

## Deployment

For Render, Railway, Fly.io, or similar PaaS:

```bash
# build command
npm install

# start command (when deploying from repository)
node src/index.js

# or when deploying from npm package
npx full-vk-mcp

# environment variables
VK_ACCESS_TOKEN=...
VK_MCP_TRANSPORT=http
VK_MCP_HOST=0.0.0.0
VK_MCP_PORT=3000        # or omit to use $PORT (Render auto-sets it)
VK_MCP_AUTH_TOKEN=...   # required for public access
VK_MCP_MODE=read        # or your chosen profile/mode
```

> **Render note:** Render provides the port via the `$PORT` environment variable. The server automatically falls back to it when `VK_MCP_PORT` is not set.

## Development

```bash
# Run tests (schema downloads automatically on first run)
npm test

# Start the server
node src/index.js
```

> **Note:** The published npm package includes runtime files only (`src/`, `README.md`, `LICENSE`, `server.json`). Tests and development files are kept in the GitHub repository.

## VK API Schema

The VK API schema is **not included** in this repository to keep it lightweight. On the first run (server or tests), it is downloaded **automatically** from the official VK repository:

```
https://github.com/VKCOM/vk-api-schema
```

The schema is saved to `vk-api-schema/` in the project root and cached for subsequent runs.

### Updating the Schema

To get the latest VK API changes, delete the cached folder and restart:

```bash
rm -rf vk-api-schema/
node src/index.js  # schema will be re-downloaded automatically
```

## Security

- **Token storage:** Use `.env` or your MCP client's secure environment variables. Never commit tokens.
- **Least privilege:** Use `VK_MCP_MODE=read` if the AI only needs to read data.
- **Section filtering:** Exclude sensitive sections like `ads`, `secure` if not needed.
- **HTTP mode security:** By default, HTTP binds to `127.0.0.1` only. If you bind to `0.0.0.0` (public), `VK_MCP_AUTH_TOKEN` is **required** — the server will refuse to start without it. Always use HTTPS in production.

## Troubleshooting

| Issue | Solution |
|-------|----------|
| `VK_ACCESS_TOKEN is required` | Create `.env` file or set the environment variable |
| `Unknown tool` | Check that the method name uses snake_case (`vk_wall_get` not `vk.wall.get`) |
| `Access denied` | Your token lacks the required VK permission scope |
| Too many tools | Use `VK_MCP_INCLUDE_SECTIONS` or `VK_MCP_MODE=read` to filter |
| HTTP `Not Acceptable` | Add header `Accept: application/json, text/event-stream` |
| HTTP `VK_MCP_AUTH_TOKEN is required` | Set auth token when binding to `0.0.0.0` |
